WALTER L. MARR, OF FLINT, MICHIGAN. ENGINE-STARTER.

Specification of Letters Patent. Application filed March 15, 1513. Serial No. 754,545.

To all whom it may concern:

Be it known that I, WALTER L. MARK, a citizen of the United States of America, residing at Flint, in the county of Genesee and State of Michigan, haveinvented certain new and useful Improvements in Engine- Starters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to means for introducing explosive charges into the cylinders of internal combustion engines for the purpose of supplying combustible fluid for the initial explosions in starting such engines.

The object of the invention is to provide simple and convenient means for forming explosive charges and introducing the same into the engine cylinders under pressure, and further to provide a suitable distributing valve for controlling the admission of the charges to the cylinders and to provide certain other new andu'seful features in the construction and arrangement of parts all as hereinafter more fully described,

reference being had to the accompanying drawings, in which- Figure 1 shows an arrangement of device in diagrammatic form to illustrate the operation of the invention, and also showin an enlarged sectional View of a distributing valve and a similar view of a vaporizer; and Fig. 2, is a front end elevation of the distributin-g valve.

While the invention is particularly adapted for use upon automobiles and other motor vehicles it may be also used upon stationary engines or in motor boats and therefore the diagrammatic arrangement shown in Fig. 1 of the drawing is not adapted for any particular use but is for the purpose of illustrating the invention and its 0 oration.

In Fig. 1, A represents the cylin ers of a /multi le cylinder engine which cylinders ma e arranged in any desired manner an the en 'ne may have any desired number of cylinders, the inlet or distributing valve B, being constructed accordingly. A tank 0 is provided for holding air under pressure,-no means being shownfor supplying the tank with compressed air, it being understood that any suitable means may be provided and operated by the engine when the same is running or any other source of power. A vaporizer D is provided and it will be understood that any WBH kD OWIi form of vaporizer may be employedv into explosive charges.

which air under pressure may be introduced from the air supply tank to vaporize gasolene contained in the vaporizer and form The vaporizer shown comprises a suitabletank or' receptacle 1 adapted to contain within its lower end a similar fuel and intermediate its ends formin a porous baffle 2 within the receptacle w ich divides the same into a lower fuel chamber 3 and an upper vapor chamber 4. Leading from the air tank C is is extended downward through the top of the receptacle 1, through the battle 2 and into the lower chamber 3 rovided with a head or spreader 6 so that the air under compression escaping from the pipe will be distributed inthe lower end of the chamber and pass up through the fuel and wall 2 into the vapor chamber 4. In bubpassing through the saturated porouswall 2 it becomes thoroughly carb'ureted and then passes fromthe top of the receptacle through a pipe 7 leading therefrom to the distributing A pressure gage 8 is provided in the pipe 7 to show the amount of pressure Mounted upon any suitable support as for example, a dash board 9 of a motor vehicle, is the distributing valve B which comprises 10 formed with a tapering bore extending inward from one end thereof. Leading into one side of the bore is a series of outlet passages l land a like inlet pashich is secured the pipe 7 leading from the vapor- Secured within the outer ends of the outlet passages 11 is a series of pipes 13 leading to the several cylinders of the m0- tor, there being one pipe for each cylinder. Within the tapered bore of the .casing 10 is with "a' circumferential a plug valve 14 which is tape'redjto correspond to the taper of the bore and is progroove 15 adapted to register with the inlet from this groove longitudinally of the plug is a spiral groove 16 which is adapted to be brought into regassages 11 by turning the plug. The expllosive mixture ene pipe 7 and inlet passage 12;fill's the groove 15'and passes into t the open end of the spiral groove 16 which ,by turning the valve is brought successively I tributed to the the explosive charges are into registry with the several outlet'passages l1, and thus the explosive mixture is several cylinders through the pipes 13 by the turning ofthevalve.

The open end ing is closed by a cap 17 secured by screws 18 to the casing and this cap is formed with a chamber 19 for a coiled spring 20-which is sleeved upon the valve stem 21 between the valve and the'end of the chamber'to hold the valve firmly seated within the tapered seat or bore of the casing and prevent leakage. The valve stem 21 passes outward througha stuffing box 22 and is provided with an operating handle 23 on its outer end. An indicator to the outer end ofthe valve stem and an 1ndicating dial 25 is supported in any suitable manner adjacent to the hand and provided with suitable indicating marks to show the position of the valve andwhich one of the cylinders of the engine 1s con-' nected with the vaporizer when the valve is turned to a particular position. The word ()if on the dial also indicates that when the indicator hand is opposite that word, that the valve is so turned that all communication between the vaporizer and the cylinders is cut olf.

A very simple and eificient starting primer for internal combustion engines is provided and by forcing-the starting charges into the engine cylinders by connecting up the vaporizer with a source of air under pressure, charges are forced into the cylinders to insure a The device is economical in its operation as formed from an accurate mixture of air and gasolene vapor, the arrangement being such that the air passing into-the vaporizer under pressure 7 is completely and thoroughly carbureted arrangement and by passing up through the body of fluid and then through the porous wall 2 which is preferably formed of several layers of felt and held between walls of wire gauze. The fluid in the chamber 3 cannot pass through the wall 2 but will saturate this wall so that the vapor chamber a will always contain a mixture of vapor and 'air which will pass directly into thecylinders of the engine upon tributing valve: 9 I

Obviously, changes may be madeQin the construction of the various parts and their I therefore placed myself to the particular form or construction shown.
